Hi Stevie,
It is quite an aggressive misfire, almost like hitting a brick wall. The fueling is textbook very very good, starts and idles/runs perfectly. I can leave it for 5months and it will start at first turn of the key.
I shall be regapping the plugs to test, I have noticed that my cts (Coolent temp sensor plug is quite loose, Could this cause misfire? I read on here somewhere that if you bridge the connector the ecu will fuel as if the engine is @ 80 Degrees. If this is the case I could warm the car up with it connected shut her down unplug sensor bridge it and see if that helps.
Cheers.
Tim.
